>&#13;      This error is occurring because you are using the new password
      encryption that comes with MySQL 4.1, while your
      <TT
CLASS="filename"
>DBD::mysql</TT
> module was compiled against an
      older version of MySQL. If you recompile <TT
CLASS="filename"
>DBD::mysql</TT
>
      against the current MySQL libraries (or just obtain a newer version
      of this module) then the error may go away.
    </P
><P
>&#13;      If that does not fix the problem, or if you cannot recompile the
      existing module (e.g. you're running Windows) and/or don't want to
      replace it (e.g. you want to keep using a packaged version), then a
      workaround is available from the MySQL docs:
